摘要: 壳聚糖是一种良好的食品生物保鲜剂,研究添加0、0.05%、0.15%、0.25%、0.35%、0.5%壳聚糖的梅鱼鱼丸在真空包装条件下0℃贮藏过程中微生物菌相和品质变化。结果表明:添加0.5%壳聚糖可以使梅鱼鱼丸的货架期明显延长;能显著抑制梅鱼鱼丸中微生物的生长,对其中的优势微生物肠杆菌、假单胞菌、微球菌/葡萄球菌等均能有效抑制(P<0.05),添加量低于0.5%则抑菌效果不明显;且pH值和总挥发性盐基氮明显降低,能显著增加鱼丸硬度,对弹性影响不大。

Abstract: Changes in the microbial community and quality of black-gill bighead croaker meatballs with added chitosan at levels of 0, 0.05%, 0.15%, 0.25%, 0.35% and 0.5% as an excellent biological food preservative were investigated during storage at 0 ℃ in a vacuum packaging environment. It wad found that adding chitosan at 0.5% could markedly extend the shelf life of black-gill bighead croaker meatballs, and inhibit microbial growth, revealing a significant (P < 0.05) inhibitory effect against the dominant microbes including Enterobacteriaceae, Pseudomonads, Micrococcaceae and Staphylococcus. No obvious antimicrobial effect was observed when chitosan was added at a level of less than 0.5%; meanwhile, both the pH and total volatile basic nitrogen of black-gill bighead croaker meatballs showed a notable decrease, the harness was remarkably elevated, and little change in the springiness was observed.
